What instrument displaced tikanga and hapū law after 1840?
Part 45 identified a mixed acquisition record and the colonial-law continuity problem. If pre-existing law was not automatically erased by a change of sovereign, the next question is exact: where is the instrument that extinguished Māori law? The record located so far does not reveal one general instrument. It reveals a staged process of recognition, containment, substitution and jurisdictional takeover.

1844: the colonial legislature expressly admits Māori usages still had force
The Native Exemption Ordinance 1844 is unusually candid. Its preamble says the desired end was that the Aboriginal Native population should eventually yield obedience to the laws and customs of England, but that this should be achieved gradually rather than through immediate and indiscriminate enforcement, so that the force of ancient usages would be weakened over time.
That language is powerful evidence against any theory that tikanga had already disappeared automatically in 1840. Four years after the sovereignty proclamation, the colonial legislature was still legislating on the premise that ancient Māori usages remained socially and juridically operative enough to require a deliberate process of transition.
1846: colonial courts were adapted to both races rather than treating one legal order as already erased
The Resident Magistrates Courts Ordinance 1846 said the law needed to be adapted to the circumstances of both races. It created special procedures for disputes involving Māori and, for civil disputes between Māori, established arbitration courts assisted by Native Assessors selected from men of authority and repute in their tribes.
Where the two Assessors agreed, they could determine the case; where they differed, enforcement required concurrence involving the Resident Magistrate and Assessors. That is not full hapū self-government, but it is evidence that the colonial system still had to accommodate Māori authority and dispute-resolution structures.
1852: the imperial constitution expressly contemplated Māori law continuing
Section 71 of the New Zealand Constitution Act 1852 is difficult to square with a theory of complete prior extinguishment. It expressly contemplated districts in which the laws, customs and usages of the Aboriginal or Native inhabitants could be maintained for their own government in relations and dealings with one another, even where those laws were inconsistent with English or colonial law, provided they were not repugnant to general principles of humanity.
The power was never brought into operation through the required Letters Patent. That non-use matters. But the statutory text itself shows that Westminster still understood Māori law as something capable of being legally maintained inside the colonial constitution.
1858: the Crown begins converting recognition into controlled colonial institutions
The Native Districts Regulation Act 1858 authorised the Governor in Council to make regulations for Native districts. Its powers included regulation of matters affecting Māori communities and the suppression of what the Act called injurious Native customs, substituting colonial remedies and punishments.
The Native Circuit Courts Act 1858 then created colonial courts specifically for districts where Native title had not been extinguished. Those courts used Resident Magistrates, Native Assessors and Māori juries, but exercised powers sourced from colonial statute.
Recognition remained
Native title, Native districts, Māori assessors, Māori juries and distinct procedures were expressly recognised.
Control shifted
The source of enforceable jurisdiction increasingly became Governor-in-Council regulation and colonial statute rather than autonomous hapū authority.
The Native Territorial Rights Act 1858 is especially revealing
That Act declared that ordinary colonial courts had no cognisance of questions concerning Māori title or occupancy as between Māori themselves over land where Native title had not been extinguished, except to the limited extent given to Native Circuit Courts under statutory regulations.
This is significant because Parliament was not saying Māori customary title had ceased to exist. It was instead deciding which colonial institution, if any, could adjudicate it.
That is a jurisdictional takeover mechanism: the customary right survives, but control over recognition and adjudication migrates into institutions constituted by the Crown.
The English Laws Act 1858 does something different
The English Laws Act retrospectively deemed applicable English law to have been in force from 14 January 1840. It therefore strengthens the colonial legal order dramatically.
But it does not contain an express clause saying:
“All Māori law, tikanga and hapū jurisdiction are extinguished.”
Its function is reception of English law. Whether a particular Māori custom survived, conflicted with English law, or remained cognisable in a particular field was left to other statutes, institutions and later judicial doctrine.
1865: general colonial court jurisdiction becomes express — but custom still survives in land
The Native Rights Act 1865 declared colonial court jurisdiction over Māori persons and property. That is one of the clearest statutory steps in extending the Queen's courts across the Māori population.
Yet the same Act expressly required Māori title to land to be determined according to the ancient custom and usage of the Māori people. In other words, the statute simultaneously universalised colonial court jurisdiction and preserved Māori custom as the governing rule for a defined legal question.
The Native Lands legislation changes the architecture
The Native Lands Acts of the 1860s created a specialist court to investigate Māori customary ownership and convert customary interests into titles recognised by the Crown-derived land system. The Native Lands Act 1865 allowed claims based on Native custom and succession under Native customs to be heard and conclusively determined by the Native Land Court.
This was not simple recognition of an untouched hapū jurisdiction. It transformed the institutional locus of decision-making. Custom remained relevant as evidence and legal rule, but the authoritative determination increasingly belonged to a statutory court whose orders could feed land into the general colonial property system.
The pattern is therefore substitution, not one clean repeal
| Stage | What happens to tikanga / hapū authority | Instrumental effect |
|---|---|---|
| 1840–1844 | Māori usages plainly continue in practice. | Colonial law begins asserting general authority but uses exemptions and gradual enforcement. |
| 1846 | Māori authority is partially incorporated through assessors and arbitration. | Customary dispute resolution is placed inside Crown-created courts. |
| 1852 | Imperial law expressly contemplates continued Māori law in Native districts. | The mechanism is never activated. |
| 1858 | Native districts, title and custom continue to be recognised. | Regulation and adjudication are increasingly vested in Governor-created statutory institutions. |
| 1865 onward | Custom survives in defined fields, especially title and succession. | General colonial court jurisdiction and statutory land institutions become dominant. |
The Waitangi Tribunal describes the process as imposition, not consensual replacement
In its Te Raki Stage 2 work, the Waitangi Tribunal concluded that the Crown's imposition of English legal concepts in the old land claims process supplanted Te Raki Māori tikanga without their consent or involvement in decision-making. The Tribunal also identified the 1852 Constitution Act and later transfer of authority to settler government as a major constitutional change that progressively undermined Māori independence.
That supports a process model: the operative change was not one extinguishing deed but the cumulative expansion of Crown institutions into fields previously governed through rangatira, hapū and tikanga.
Modern law confirms that tikanga was not legally annihilated
The Supreme Court's 2022 decision in Ellis v R treated tikanga as part of the values of New Zealand common law and engaged directly with its place in the development of the law. Modern Supreme Court jurisprudence has therefore rejected the old premise that tikanga is legally irrelevant merely because the common-law state exists.
This does not restore a separate general hapū jurisdiction outside statutes and courts. It does, however, make one historical proposition increasingly difficult to maintain: that tikanga was wholly extinguished in 1840 and had to be recreated from nothing in modern law.
Finding 46
The next inquiry should isolate the decisive institutional transfer: when did authority over Māori affairs move from the imperial Governor — who was supposed to stand between Māori and the settler population — into responsible settler government, and what happened to the Crown's separate obligations when that transfer occurred?
